Triggering
The Port Range Triggering screen allows the Router to
watch outgoing data for specific port numbers. The IP
address of the computer that sends the matching data is
remembered by the Router, so that when the requested
data returns through the Router, the data is pulled back
to the proper computer by way of IP address and port
mapping rules.

Applications and Gaming > DMZ
The DMZ feature allows one network computer to be
exposed to the Internet for use of a special-purpose
service such as Internet gaming or videoconferencing.
DMZ hosting forwards all the ports at the same time to
one PC. The Port Range Forwarding feature is more secure
because it only opens the ports you want to have opened,
while DMZ hosting opens all the ports of one computer,
exposing the computer to the Internet.
